SPECIFICATION forming part of Letters Patent No. 792,630, dated June 20, 1905.

Application filed November 28, 1903. Serial No. 183.054.

To all whom it may concern:

Be it known that I, CLARENCE L. TAYLOR, of

Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Ingot-Strippers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

IO My invention relates to an improvement in ingot-strippers, the object being to provide a stripper designed to be suspended from a crane or other support; and the invention consists in the parts and combinations of parts, as

5 will be more fully explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of my improved crane. Fig. 2 is a view in longitudinal section. Fig.

3 is a view in plan, partly in section. Fig. 4

is a view in section, showing the key connection between the bar and sleeve; and Fig. 5 is a view in section similar to Fig. 2, but showing the mold-grasping arms carrying the 5 mold partly stripped from the ingot and also showing the carrying or supporting bar in the form of a rack.

1 represents the combined carrying or supporting bar and plunger, provided at its up- 3 per enlarged end 2 with an eye through which the hook on the bar-carrying cable or chain (not shown) passes. The upper end of this bar 1 is preferably made separate from the bar proper and is secured thereto by a a5 threaded shank 4, as shown in Fig. 2, while the lower end is provided with a socket to receive the stem 5 of the block 6. The upper end of this bar is screw-threaded and preferably provided with twin threads, as shown,

and this screw-threaded portion is embraced by the combined elongated nut and screw 7, the female threads on the part 7 engaging the threads on the bar 1, while the external and preferably twin threads on the combined nut and screw 7 are engaged by the internal threads on the sleeve 01' carrier 8.

From the construction thus far described it will be apparent that if the combined nut and screw 7 were restrained against endwise movement a rotary movement of the combined 5 nut and screw would force the bar 1 longitudinally in one direction and the carrier 8 in the other; but as the bar when in operation is suspended, and consequently incapable of longitudinal movement except when lifted or lowered by its suspending cable or chain, it follows that when the combined nut and screw 7 is rotated it moves longitudinally in one direction on the rod 1, while the sleeve or carrier 8 moves longitudinally in the same direction on the part 7, thus imparting an accelerated movement to the sleeve or carrier which carries the mold-engaging arms 9.

Formed integral with the part 7, near the upper end of the latter, is the flange l0, and 5 resting on the flange and keyed to the part 7 is the worm-wheel 11. This worm-wheel is engaged by two parallel worm-shafts 12, located on opposite sides of the apparatus and mounted in the frame 13, carried on the up- 7 per face of the worm-wheel 11. This frame 13 embraces the hub of the worm-Wheel 11 and rests on the latter adjacent to the hub, its upper end being in the form of a hood 14 made in sections to cover and inclose the wheel 11, while the portion thereof below the hood 14 is cylindrical in shape and slidingly embraces the sleeve or carrier 8 and is keyed to the latter, as at 15, to prevent any independ ent rotary movement of these parts.

Secured to the lower end of the frame 13 are the platforms 16, on which are mounted the motors 17, the armature-shafts 18 of which are geared up to their respective worm-shafts 12 by the pinions 19 and 20, the former of 5 which are on the armature-shafts of the motors, While the latter are secured to the wormshafts. By providing two motors and locating them on opposite sides of the apparatus the latter will be balanced and the parts there- 9 of always in a position to engage the ingot and the engaging ears or lugs on the mold.

The lower end of bar 1 is connected by splineand-groove connection to sleeve or carrier 8, as shown in Fig. 4, and as the carrier 8 is keyed to frame 13 it follows that the only part free to rotate independently of the other parts is the combined nut and screw 7.

rier having internal threads engaging the external threads on the combined screw and nut, motor and gearing for rotating the latter, and mold-engaging arms carried by the sleeve or carrier.

8. In an apparatus for stripping molds from ingots the combination with an ingot-engaging bar having external threads and a sleeve or carrier having internal threads, the said carrier and bar being connected by a splineand-groove connection, of a combined nut and screw interposed between the bar and carrier, its screw-threads engaging the threads of both of said parts and meansfor rotating said combined nut and screw.

9. In an apparatus for stripping molds from ingots the combination with an ingot-engaging bar screw-threaded externally, a sleeve or carrier embracing said bar and provided with internal threads, a spline-and-groove connection between the sleeve and bar and mold-engaging arms depending from the sleeve, of a combined nut and screw interposed between the bar and sleeve and having teeth engaging the teeth of both of said parts, two motors located on diametrically opposite sides of the bar, and gearing connecting both motors with the combined nut and screw.

10. In an apparatus for stripping moldsfrom ingots the combination with a depending rod, an ingot-engaging bar, and a sleeve or carrier, of mold-engaging arms on said sleeve or carrier, intermeshing sectors rigid with the arms,

a second sector rigid with one of said arms, and a lever pivoted to the sleeve or carrier and provided at one end with teeth engaging said second sector, the free end of said lever adapted to engage a stop or abutment on said depending rod.

11. The combination with an ingot-engaging bar having external threads a combined nut and screw on said bar, and an internallythreaded sleeve or carrier embracing the combined nut and screw, of aworm secured to the upper end of said nut and screw, a platform supported and carried by the latter and motors and gearing carried by the platform.

12. In an apparatus forstripping molds from ingots, the combination with an ingot-engaging bar having external threads, of a combined nut and screw on the bar, a sleeve or carrier having internal threads engaging the external threads on the combined nut and screw, means for rotating the latter and moldengaging arms depending fromthe sleeve or carrier In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
